Abstract

The invention relates to anti-pitting self-repairing gear grease. The anti-pitting self-repairing gear grease comprises, by weight, 92-97% of a gear grease body and 3-8% of a self-repairing addition agent. According to calculation of the total mass of 100%, the self-repairing addition agent comprises, by weight, 50-70% of antioxidant, 10-25% of an anti-wear agent, 5-10% of an extreme pressure agent and 5-20% of organic molybdenum. The anti-pitting self-repairing gear grease has excellent antioxygen performance and extreme pressure wear resisting performance at different temperatures, can effectively prevent the surface of a gear from generating pitting, and can have a function of repairing the worn surface of the gear to a certain degree, so that the service life of the gear is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, in particular to a gear lubricating grease, in particular to an anti-pitting self-repairing gear lubricating grease. Background technique [0002] Gear transmission is one of the most important and widely used transmission forms in modern machinery. In order to reduce the friction and wear during the working process of the gears and prolong the service life of the gears, lubricants are needed. Closed industrial gears generally use industrial gear oil, and open gears generally use gear grease. Asphalt lubricants were often used in the early open gear lubrication. With the improvement of equipment development requirements for lubrication, many new and high-performance gear greases have been developed and used in industrial production. [0003] The current mainstream gear grease is composed of thickener, base oil and various additives. Thickeners include non-soap-based thickeners such as b...
